VALVE-COUPLING.

Specification of Letters Patent.

Patented Dec. "2', 1915.

Application filed October 31, 1314-. Serial No. 869,606.

T0 (4% whom it may concern:

Be it known that l, CARL MERGER, a citizen of the United Sitates, residing at Sperry, in the county of Tulsa and State of Oklahoma, have invented certain new and useful Improvements in Valveiouplings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention colnprehends certain new and useful improvements in valve couplings and has for its primary object to providea coupling of this character which will be especially adapted for coupling together the valve piston and the standing valve in the working barrel ofoil wells.

The invention has for another object to provide a valve coupling which will be constructed in such manner that it may be readily engaged with or disengaged from the standing valve.

The invention has for a further object to provide a coupling of this character formed of two pieces, one of which may be rotated upon the other and secured to the standing valve or locked against rotation upon the second part for the purpose of pulling the standingvalve at the same time as the pulling of the valve piston.

The invention has for a further object to provide a two part coupling of this character which will be of exceedingly simple construction and operation and which may be readily secured to the valve piston and the standing valve of oil well apparatus and engage with or disengage from one another, as occasion may require.

The invention has for a further object 'to generally improve and simplify the construction and operation of devices of this character and increase the efficiency thereof without materially increasing the cost of the same.

With the aboye and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my in vention, reference is to be had to the following description and accompanying drauings, in whichof my coupling adapted to be secured to the sanding valve, and Fig. 1 is a bottom end view of the cylindrical member of the cou-' pling.

Referring more particularly to the drawmg in which similar reference characters designate corresponding parts throughout the several views, 1 designates the working barrel of an oil well apparatus within which are positioned the standing valve 2 and the valve piston 3, which latter is mounted upon the sucker rod in the usual manner. It will also be understoodthat the standing valve and the valve piston 3 are of the usual construction and threaded in the collar 5 connecting the upper end of the upwardly converging arms 6 of the valve 2 is the shank o-fmy coupling pin 7, upon the opposite sides of the upper end or head 8 of which are formed the vertical longitudinal ribs 9.

Threaded upon the lower end of the valve piston 3 is my coupling sleevelO which has its upper end interiorly threaded, as shown at 11, and is provided with the circular flange 12 immediately below the threaded portion 11, said flange 12 being provided in its lower edge at diametrically opposite points with upwardly extended cut-away portions 13 to receive the upper end of the vertical or longitudinal ribs 9 on the head 8 of the coupling pin 7 when the coupling pin head is within the sleeve 10 and the latter forced downwardly after being turned to bring the cut-away portions 13 of the flange 12 above the ribs 9, as will be read ily understood by referring to the drawings. The sleeve also has formed in its lower end a circular inner flange 14 which has opposite portions cut-away to form the guide slots 15 for theoribs 9 to permit the sleeve 10 to be engaged with or disengaged from the head 8 of said coupling pin 7 The lower flange 14 is also provided between the guide slots 15 with substantially V-shaped recesses 16 formed in its upper edge by cutting away portions thereof so that after the sleeve '10has -been'moved to position over coupling sleeve 10.

l letting the coupling sleeve drop over the couthe head 8 of the coupling pin 7 to bringthe head 8 between theflanges 14 and 12, the sleeve 10 may be given a quarter turn and .then drawn upwardly to; place the lower end of the ribs 9 in the recesses 16 and thereby lock the coupling pin 7 for rotation with the It will be understood that the cut-away portions 13 ofthe upper flange 12 are between the recesses 16 and in alinement' with the guide slots 15, whereby whenthe sleeve 10 is forced downwardly over the heads and moved to its lowermost position, the upper end of the ribs Swill be engaged in the cut-.

away portions 13 of the upperfiange12and the coupling pin 7 thereby'locked for rotation with the sleeve 10. Upon upward movementiof the coupling sleeve10, however, said sleeve 10 will be drawn fromover V the head 8, the ribs 9 of said head 8 passing ;.out by way of the guide slots 15 in the lower "flange 1 1;

From the foregoing it will be readily seen that the coupling pin 7 and coupling sleeve 10 maybe readily attached to the standing valve and valve piston respectively and the standing valve may be pulled'at the same time the valve piston is pulled. A great advantage of this device is'that in case the sucker rod becomes unscrewed by accident,

pling' pin, they may be screwedtogether again without coupling together the sleeve and pin, it being impossible to turn the coupling sleeve 10 as the ribs 9 of the head 8Qof the'coupling pin? are engaged inthe cutaway portions 3130f the upper flange 12 the clamping valve, however, all that is nec essary s to perimt the coupllng sleeveto drop over the coupling p1n, ra1se the coupling pin slightly and then give the sucker rods about a quarter turn, thereby coupling together the coupling sleeve 10, and coupling pin 7, making itpossible to pullboth valves at the same time. Still another ad vantage ofthis device is that in caseyou couple onto a standing valve which has become East and cannot be pulled, it is just as easy to uncouple them as it them together;

While the preferred embodiment of the invention hasbeen shown and illustrated, it will be understood that minor changes in the details of construction and arrangements of parts may he made without departing was to couple frointhe spirit and scope 'offthe invention as claimed or sacrificing any of the advantages thereof. v v

hat is claimed is:

1. A coupler of the character. described including a coupling sleeve having upperv and lowerfianges formed there n, the lower a flange being provided with opposite guide,

grooves, said flanges having cut away portions, and a coupling pin having longitudlnal ribs formed on its headjformovement through "the guide grooves of "the lower flange and engagement in the cut-away portions of the upper and lower flanges of said coupling sleeve. 7 3 4: V a; 2-. A coupler ofthe class described comprising a coupler sleeve for engagement with a vz lve, arcoupl'ing pin for engagement with the second valve and having a head provided with longitudinal. ribs, said coupling sleeve having an interior flange with guide slots extended therethro'ugh .at diametrically opposite points, 'saidlowerfiangehaving substantially V-shaped recesses in its upper edge to receive the ribs of the coupling pin and thereby lock the same with the coupling sleeve, and'an interior upper flange carried by saidcoupling sleeve'and provided with said rib receiving recesses in its lower edge at right angles to 'the'recesses in the lower flange andin alinement with the guide slots of thelowerfiange, the upper end of said coupling sleeve being interiorly threaded while the lower end ofthe coupling pin is eXteriorly threaded. c In testlmonywhereof I afilx ny signature in presence oftwo WltlleSSBS;
